INSPECTION PROCEDURE
HINT:
Read freeze frame data using the hand−held tester. Freeze frame data records the engine conditions when
a malfunction is detected. When troubleshooting, freeze frame data can help determine if the vehicle was
running or stopped, if the engine was warmed up or not, if the air −fuel ratio was lean or rich, and other data
from the time the malfunction occurred.
1 CHECK OTHER DTCS OUTPUT(IN ADDITION TO DTC P0234, P0299 AND/OR

(a) Connect the hand −held tester to the DLC3.
(b) Turn the ignition switch to ON and turn the hand −held tester ON.
(c) Select the item ”DIAGNOSIS / OBD/MOBD / DTC INFO / CURRENT CODES”.
(d) Read DTCs. Result:

3 CHECK VACUUM HOSES(CHECK VACUUM BETWEEN TURBOCHARGER −VRV
FOR TURBO CHARGER)
(a) Using a three −way connector, connect a vacuum gauge to the hoses between the E −VRV and turbo-
charger.
(b) Warm up the engine coolant temperature to above 75 ˚C (167 ˚F).
(c) Check the vacuum at the engine speed of 900 rpm.

DTC P0200 INJECTOR CIRCUIT / OPEN
HINT:
S For more information on the EDU, see page 05 −255.
S If P0200 is present, refer to the diagnostic trouble codes (DTCs) table for the fuel system on page
05 −255.
CIRCUIT DESCRIPTION
The EDU has been adopted to drive the injector at high speeds. The EDU has realized the high −speed driv-
ing under high −pressurized fuel conditions using the DC/DC converter that provides a high −voltage, and the
quick −charging system.
Soon after the EDU receives an injection command (IJT) signal from the ECM, the EDU responds to the com-
mand with injector injection confirmation (IJF) signal when the current is applied to the injector.

INSPECTION PROCEDURE
HINT:
SIf P0200 and P1271 are present simultaneously, there is open in the INJF wire harness between the
EDU and ECM, or there is open in the wire harness for both injector and pressure discharge valve.
SRead freeze frame data using the hand−held tester. Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the
vehicle was running or stopped, if the engine was warmed up or not, if the air−fuel ratio was lean or
rich, and other data from the time the malfunction occurred.
